Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Green tomatoes
Form the bulk of the pickle and absorb the vinegar's tang as it sits.
Onions
Add sweetness and savory depth that balances the sharp vinegar.
Peppers
Contribute mild heat and fresh, vegetal flavor to the pickle.
Vinegar
Provides the acidity that preserves and sharpens the pickled vegetables.

The step that matters

Cook until tender but not broken. Cooking the vegetables just enough softens their cell walls so they take up the vinegar, while overcooking causes them to fall apart and turn mushy, leaving a limp, cloudy pickle.

Swap the onion

How well each one fits the dish's main ingredients (tomato, pepper, vinegar):

  1. Capsicumfits better
  2. Cucumberfits better
  3. Mustardfits better
  4. Onionthe original

Fit is the average pairing score against tomato, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
